In the supermarket, in the market, there are crowds of people rushing to buy, rice stalls are quickly sold out, and durable vegetables, fruits and eggs are also bought and bought like money. Do acquaintances ask "Do you buy grain, buy more [teeth]?"
In fact, I would like to say that it is appropriate to hoard some necessities of life, and blind mass purchases are really unnecessary. It may be used as a drill for disaster prevention and mitigation, where everyone comes to exercise and develop the habit of stockpiling the right amount of daily necessities.
